There exists a world within our world. A world beneath what we call cyberspace. A world protected by firewalls, passwords and the most advanced security systems. In this world we hide our deepest secrets, our most incriminating information, and of course, a whole lot of money. This is the world of "Swordfish." The world's most dangerous spy is hired by the CIA to coerce a computer hacker recently released from prison to help steal $6 billion in unused government funds.
